HI and welcome...You might want to post an introduction in the NEW MEMBERs area and let us know where you're from and some more details about your GMC..
Anyway..my 2015 has some exposed areas too under the seats as well..It really depends on how far back the seat is put, to how much you see..If the carpet is loose I would go back to the dealer and show them your concerns..
